- IThis invention` relates to devices thatcan be placed in an orchardheater as a heating medium.

,Y Y One of the objects' ofthis invention is toA J provide a heatingmedium that iscomplete I in itself as to priming igniting and' heatingfora certain desired or required length of time. l

VAnother object is to provide'distinct vfillers and reiillers that canbe` placed in orchard heaters by unskilled help and assure. a heating ina certain desired and required mannel Another l*object is to providepositive indications by which the filler is placed posi'- tively in acorrectmannerin to a heater to assure arproper ignition and a proper'burnm f v (ther'objects will appear from the followingdescription andappended claims as well as from the accompanying drawing, in which- Fig.l is a vertical midsectional view of a typical orchard heater in whichsolid or the like fuel is burned,v having laliller indicated therein ofa certain form. tol leave a desired space for draft purposes, the lillerbeing broken away at points to show inside parts and being generallydesigned to operate according to this invention.

2 is a cross section on line 2 2 of liglig. 3 is a fragmentary sideelevation of a filler of a slightly modified form, the broken awaysection illustrating that the inside structure of this modified form isof equal or substantially similar structure throughout the whole lengthof the filler instead of different grade as indicated in theillustration of Fig. l.

Orchard heaters are most generally ignited and heated either with liquidor comparatively solid fuel.

In either case as now most commonly practiced the heater is filled orprepared for the heating during day-time in order that during the nightwhen the temperature is normally the lowest a mere ignition of thelprepared v fuel in the heater remains necessary to pro- 50 duce therequired heat fo-r the orchard. y

However, conditions are liable to make it impossible to.` so prepare Vayheater during day-time, or .weather conditions may necessitate anextended heating-during exceptionally severe andv long periods, f'

1 To insure against all eventual1ties,this i11-A vention features ameansthat'facilitates-instant ignition and heating of an orchardfheaterregardless of weather conditions or other possibilities. v if Y f iConsidering the requirements for a heater of the typ-e illustrated in Fig. l in the drawing, in which the grate Zlis provided to supportcomparatively solid fuels such as wood,

coal, paper, asphalt, coke, and burnable rub- 65 bish and in whichcertain draft holes', 6 and 'l' are provided in order that thel fuel canbe caused to'burn m a certain manner;v av certain filler 8 is roughlyoutlined in this connection with its'outer 'contours 9 spaced from 70the inside walls of the heater l0, so that a draft of cool aircancirculate around the v filler S to escape` through the topmost holes7, the other holes5 and@ being preferably placed so as'to face theincoming draft of 75 Any filler or 'burning or heating medium for such aheater is preferably of such a nature to assure a heating for a certainperiod, and on 'the other handto facilitate a 8 proper ignition underall conditions.

Such a filler consists preferably of fa burnable casing 11 of paper,cloth, or burnable composition for one thing and burnable material inthe inside of the casing 1l.

The inner burnable material is for one purpose in the large portion ofcoarser and slower burning grade and in its smaller portion of finer andeasier igniting grade, while for another purpose it is throughout of thesame ycoarse grade. The mixed grade is used most commonly, in Fig. l,the ner grade being yindicated at the top at l2 and the coarser p may bedesirable over a comparatively longv1 period as in case of a light frostduring all of a night. In the rst case, the primer should preferably beplaced at the bottom to assure an immediate burning of the whole matterof the iller; while in the second case, the primer should be placed atthe top sothat the material will merely smolder slowly froml` the top ondownwardly.

To assure a proper placing of the liller into the heater the filler isprovided with indicating means, as in form of a solid bar or arrowpointing in the direction in which the filler normally should be placed,as indicated on the side of the filler at 14, at the top end at 15,another indicating means being shown as near the'primer. Either Vofthese indicating means or similar suitable means can of coursebeprovided, the means as illustrated merely being used to explain theprincipleof this feature, such indicating means however are preferablyof a form to be easily graspable even inthe dark in order to avoid amisplacing. v y l In case of eXtreme cold weather conditions lastingover an unexpected long period of time, in which case a refilling of theheater should become rnecessary without interruption, a special refilleris provided as illustrated in Fig. 3, having the same coarse and slowburning but strong heat producing medium 13 throughout its length fromone end 1.6 to the opposite end 17. This -type of a liller shouldpreferably have equal indicating marks on both ends' as indicated at 18,by which such a reliller may be recognized. A suspending member, as inform of a hook 19 is provided on all fillers and relillers, by whichthis device may be suspended from the branch of a tree instead of beingplaced on the eventually damp ground.

' It must be understood that a filler of this type can be used on anygrate, or in a stove i lilling placed near thevtop of said filling inVsaid casing, whereby when the kindler is ignited at the top of saidpackage the fuel is caused to progressively'burn downwardly in saidheater covering an extended heating periodV and said package of fuelbeing spaced inwardly from said casing. whereby an ,upward draft of airis created between the-inner wall of said casing and the Vside of saidpackage to assist combustion of fuel in said package. 2. In combination,a heater having a draft opening in its side wall and a package offuelplaced in said heater and yextending above said draft opening, saidpackagelcomprising, a burnable casing having av filling ofinflammablematerial and a kindler offlmore readily inflammable material than thefilling placed near one end of said package in said casing7 whereby whentheV kindler is ignited the fuel is caused to progressively rburn insaid casing covering an extended period', and said package of fuel beingspaced inwardly from said casing whereby lan upwarddraft of airiscreated inwardly through ysaid passage and upwardly between theinner'w'all of said casing and the wall of said package to assistcombustion of fuel in the'package. In testimony that I claim the.foregoing as my invention I have si edmy name. y
